    Streptococcus suis is a Gram-positive cocci bacterium that are found mainly in pigs and can be transmitted to human through pigs or pork exposure. The disease is mainly found among occupations involving swine contact in western countries whereas in Asia the disease is usually contracted through raw pork consumption. In this case report, we present a case of a middle-aged Thai man who acquired the infection from raw pork consumption. He presented with endogenous endophthalmitis with infective spondylodiscitis, sepsis and meningitis and later developed blindness of the right eye and permanent bilateral hearing loss disseminated from S. suis infection. Our report suggests that S. suis infection be considered as a causative factor in patient presenting with established clinical symptoms and predisposing factors. Cultural habit of eating raw pork should be taken into account especially in Asian countries.

    Cornual pregnancy happens when implantation occurs in the cavity of a rudimentary horn of the uterus, which may or may not be communicating with the uterine cavity. The diagnosis of cornual pregnancy remains challenging, and rupture of a cornual pregnancy usually causes massive bleeding. Early diagnosis and treatment, therefore, are very crucial and key to prevent mortality. Historically, the management of cornual pregnancies included wedge resection through open surgery or even hysterectomy. In this case report, we would like to highlight a case of late second trimester cornual pregnancy, at 19-week and 3-day gestation, which was managed laparoscopically.

    Choanal atresia is an uncommon malformation of the upper airway. Bilateral choanal atresia usually detected earlier as it is often associated with severe asphyxia immediately after birth. The diagnosis is often delayed in unilateral type, and mostly presented with unilateral chronic nasal discharge. This condition is rarely encountered but should be considered as a possible differential diagnosis of persistent nasal discharge. We present a case of unilateral congenital choanal atresia in a 4-month-old baby girl presented with persistent unilateral nasal discharge. Diagnostic investigation and possible surgical treatment techniques were discussed.

    PMID: 30846668
    Dermatofibrosarcoma protuberans (DFSP) is a slowgrowing, locally invasive tumour of the dermis. It commonly presents in the trunks and proximal extremities but is seen to a lesser extent in the head and neck regions. We present a case report of a recurrent DFSP in a 48-year-old Iban woman at the occipital region. The patient underwent wide local excision and removal of outer table of cranium, dressing followed by split thickness skin graft. Histopathological examination confirmed dermatofibrosarcoma protuberans with clear lateral surgical margins and a deep margin of 0.5mm. She is currently undergoing radiotherapy and is planned for 50Grey 25cycles.

    INTRODUCTION: Cardiovascular diseases (CVDs) are among the most frequently identified comorbidities in hospitalized patients with COVID-19. Patients with CV comorbidities are typically prescribed with long-term medications. We reviewed the management of co-medications prescribed for CVDs among hospitalized COVID-19 patients.

    AREAS COVERED: There is no specific contraindication or caution related to COVID-19 on the use of antihypertensives unless patients develop severe hypotension from septic shock where all antihypertensives should be discontinued or severe hyperkalemia in which continuation of renin-angiotensin system inhibitors is not desired. The continuation of antiplatelet or statin is not desired when severe thrombocytopenia or severe transminitis develop, respectively. Patients with atrial fibrillation receiving oral anticoagulants, particularly those who are critically ill, should be considered for substitution to parenteral anticoagulants.

    EXPERT OPINION: An individualized approach to medication management among hospitalized COVID-19 patients with concurrent CVDs would seem prudent with attention paid to changes in clinical conditions and medications intended for COVID-19. The decision to modify prescribed long-term CV medications should be entailed by close follow-up to check if a revision on the decision is needed, with resumption of any long-term CV medication before discharge if it is discontinued during hospitalization for COVID-19, to ensure continuity of care.

  9. Fulltext Real-Time Stress Assessment Using Sliding Window Based Convolutional Neural Network
    Naqvi SF, Ali SSA, Yahya N, Yasin MA, Hafeez Y, Subhani AR, et al.
    Sensors (Basel), 2020 Aug 07;20(16).
    PMID: 32784531 DOI: 10.3390/s20164400
    Mental stress has been identified as a significant cause of several bodily disorders, such as depression, hypertension, neural and cardiovascular abnormalities. Conventional stress assessment methods are highly subjective and tedious and tend to lack accuracy. Machine-learning (ML)-based computer-aided diagnosis systems can be used to assess the mental state with reasonable accuracy, but they require offline processing and feature extraction, rendering them unsuitable for real-time applications. This paper presents a real-time mental stress assessment approach based on convolutional neural networks (CNNs). The CNN-based approach afforded real-time mental stress assessment with an accuracy as high as 96%, the sensitivity of 95%, and specificity of 97%. The proposed approach is compared with state-of-the-art ML techniques in terms of accuracy, time utilisation, and quality of features.

  11. Multicentre laboratory evaluation of Brugia Rapid dipstick test for detection of brugian filariasis
    Rahmah N, Shenoy RK, Nutman TB, Weiss N, Gilmour K, Maizels RM, et al.
    Trop Med Int Health, 2003 Oct;8(10):895-900.
    PMID: 14516300
    A multicentre evaluation of the Brugia Rapid dipstick test was performed using 1263 serum samples in four international laboratories, i.e. T.D. Medical College (TDMC, India), National Institutes of Health (NIH, USA), Swiss Tropical Institute (STI, Switzerland) and Leiden University Medical Centre (LUMC, Netherlands). In comparison with microscopy, the dipstick demonstrated sensitivities of 97.2% (70 of 72) at TDMC, 91.6% (175 of 191) at LUMC and 100% (six of six) at STI. Sera of chronic patients showed a positivity rate of 11.3% (19 of 168) and 61.2% (71of 116) at TDMC and LUMC, respectively. All 266 sera of non-endemic normals from STI, NIH and LUMC tested negative with the dipstick. At LUMC, sera of 'endemic normals' (amicrofilaraemics with no clinical disease) from an area with approximately 35% microfilaria positivity showed 60.8% positive results (31 of 51), thus demonstrating the likelihood of many cryptic infections occurring in this population. Specificities of the test with Onchocerca volvulus sera were 98.8% (80 of 81) and 100% (10 of 10) at the NIH and STI, respectively; while specificity with Loa loa sera at the NIH was 84.6% (44 of 52). At the STI, the dipstick test also demonstrated 100% specificity when tested with 75 sera from various protozoan and helminthic infections.

  12. Large breast lump with bloody nipple discharge: benign intraductal papilloma
    Cheah SD, Imi Sairi AH
    BMJ Case Rep, 2020 Nov 04;13(11).
    PMID: 33148555 DOI: 10.1136/bcr-2020-236818
    A 32-year-old woman presented with a 3 cm×3 cm left breast lump associated with bloody nipple discharge during her early pregnancy. Examination and ultrasonography showed benign features, whereas core needle biopsies revealed a benign papilloma. Six months after her delivery, a 6 cm×6 cm benign papilloma was completely excised via circumareolar incision. The majority of intraductal papillomas are small; however, they can also present as a large mass rarely. We should be wary of a malignant papillary lesion when there is the presence of atypia on core needle biopsy or imaging-histology discordance. A concordant benign papilloma with benign imaging findings is otherwise reassuring. Clinicians need to be aware of this uncommon presentation of large intraductal papilloma as a complete curative excision can be achieved through a cosmetically placed incision.

    The coronavirus disease (COVID-19) pandemic has impacted the economy, livelihood, and physical and mental well-being of people worldwide. This study aimed to compare the mental health status during the pandemic in the general population of seven middle income countries (MICs) in Asia (China, Iran, Malaysia, Pakistan, Philippines, Thailand, and Vietnam). All the countries used the Impact of Event Scale-Revised (IES-R) and Depression, Anxiety and Stress Scale (DASS-21) to measure mental health. There were 4479 Asians completed the questionnaire with demographic characteristics, physical symptoms and health service utilization, contact history, knowledge and concern, precautionary measure, and rated their mental health with the IES-R and DASS-21. Descriptive statistics, One-Way analysis of variance (ANOVA), and linear regression were used to identify protective and risk factors associated with mental health parameters. There were significant differences in IES-R and DASS-21 scores between 7 MICs (p<0.05). Thailand had all the highest scores of IES-R, DASS-21 stress, anxiety, and depression scores whereas Vietnam had all the lowest scores. The risk factors for adverse mental health during the COVID-19 pandemic include age <30 years, high education background, single and separated status, discrimination by other countries and contact with people with COVID-19 (p<0.05). The protective factors for mental health include male gender, staying with children or more than 6 people in the same household, employment, confidence in doctors, high perceived likelihood of survival, and spending less time on health information (p<0.05). This comparative study among 7 MICs enhanced the understanding of metal health in the general population during the COVID-19 pandemic.

    Many HIV-infected individuals do not enter health care until late in the infection course. Despite encouraging earlier testing, this situation has continued for several years. We investigated the prevalence of late presenters and factors associated with late presentation among HIV-infected patients in an Asian regional cohort. This cohort study included HIV-infected patients with their first positive HIV test during 2003-2012 and CD4 count and clinical status data within 3 months of that test. Factors associated with late presentation into care (CD4 count <200 cells/μl or an AIDS-defining event within ±3 months of first positive HIV test) were analyzed in a random effects logistic regression model. Among 3,744 patients, 2,681 (72%) were late presenters. In the multivariable model, older patients were more likely to be late presenters than younger (≤30 years) patients [31-40, 41-50, and ≥51 years: odds ratio (OR) = 1.57, 95% confidence interval (CI) 1.31-1.88; OR = 2.01, 95% CI 1.58-2.56; and OR = 1.69, 95% CI 1.23-2.31, respectively; all p ≤ 0.001]. Injecting drug users (IDU) were more likely (OR = 2.15, 95% CI 1.42-3.27, p < 0.001) and those with homosexual HIV exposure were less likely (OR = 0.45, 95% CI 0.35-0.58, p < 0.001) to be late presenters compared to those with heterosexual HIV exposure. Females were less likely to be late presenters (OR = 0.44, 95% CI 0.36-0.53, p < 0.001). The year of first positive HIV test was not associated with late presentation. Efforts to reduce the patients who first seek HIV care at the late stage are needed. The identified risk factors associated with late presentation should be utilized in formulating targeted public health intervention to improve earlier entry into HIV care.

  16. Clinical and radiological features of imported chikungunya fever in Japan: a study of six cases at the National Center for Global Health and Medicine
    Mizuno Y, Kato Y, Takeshita N, Ujiie M, Kobayashi T, Kanagawa S, et al.
    J Infect Chemother, 2011 Jun;17(3):419-23.

    Chikungunya fever (CHIKF) is currently distributed in Africa and in South and Southeast Asia; outbreaks have occurred periodically in the region over the past 50 years. After a large outbreak had occurred in countries in the western Indian Ocean region in 2005, several countries reported cases of CHIKF from travelers who had visited affected areas. In Japan, there have been only 15 cases of CHIKF patients so far, according to the National Institute of Infectious Diseases. Therefore, to evaluate the clinical and radiological features associated with the disease, we describe 6 imported cases of CHIKF. All of the patients had had prolonged arthralgia on admission to our hospital, and diagnosis was confirmed with specific antibodies by using an IgM-capture enzyme-linked immunoassay and a plaque reduction neutralizing antibody assay. Magnetic resonance imaging (MRI) of one patient revealed erosive arthritis and tenosynovitis during the convalescence stage. Clinicians should be aware of the late consequences of infection by the chikungunya virus (CHIKV) and recognize the possible association of subacute and chronic arthritis features. In addition, competent vectors of CHIKV, Aedes aegypti, can now be found in many temperate areas of the eastern and western hemispheres, including Japan. This fact raises concern that the virus could be introduced and become established in these areas. This necessitates an increased awareness of the disease, because imported cases are likely to contribute to the spread of CHIKV infection wherever the competent mosquito vectors are distributed.

    Urinary bladder tuberculosis (UB-TB) is one of the gravest public health issues of renal TB, and it is diagnosed with <50% of urogenital TB. Unsatisfactory and delayed diagnosis with imprudent medications for bladder TB frequently resulted in several urinary and complications, including contraction of the UB. The objectives of this research were to build awareness among medical professionals and subsequently minimize the sufferings of patients. This was a case report-based study regarding UB-TB. All routine tests for cystitis were conducted. In addition, 24-h urine sample for TB identification, including a polymerase chain reaction test, was performed. Twenty-four hours of urine sample revealed confirmatory findings of TB. The patient had responded well with the national TB guideline-designated medication. Recurrent cystitis had a higher possibility of tuberculous origin. Medical doctors must rethink when a patient visited multiple times for cystitis for the etiology of the disease.

    Florid papillomatosis (FP) of the nipple, or nipple adenoma, is a rare breast tumour, affecting middle-aged group population. A 46-year-old woman presented to us with a cauliflower-like FP of the right nipple with no blood stained discharge or breast lump. FP can be mistaken clinically for Paget's disease and occasionally misinterpreted as invasive ductal or intraductal carcinoma. Extensive intervention, correct diagnosis and prompt treatment are essential. Any breast pathology requires triple assessment including FP of the nipple. Once the diagnosis of ductal carcinoma is excluded, simple complete excision can be undertaken. This is to ensure complete obliteration of disease recurrence and preservation of cosmetic result. We discuss the pathology and psychosocial aspects of FP.

    PMID: 25801261
    Angiostrongylus cantonensis is the most frequent cause of eosinophilic meningitis in humans in Thailand and worldwide. Because of difficulty of recovering the Angiostrongylus larvae from infected patients, detection of parasite-specific antibodies is used to support clinical diagnosis. This study tested serum samples from eosinophilic meningitis patients and individuals at risk of infection with A. cantonensis to evaluate a recently developed simple and rapid dot-immunogold filtration assay (DIGFA) for detection of specific antibodies against A. cantonensis. Purified 31-kDa glycoprotein of A. cantonensis and protein A colloidal gold conjugate were employed to detect the 31-kDa anti-A. cantonensis antibody in patients sera from the parasite endemic areas of northeast Thailand. The results were compared with those obtained by dot-blot enzyme-linked immunosorbent assay (ELISA) with 31-kDa A. cantonensis antigen. The overall positivity rate of DIGFA and dot-blot ELISA for A. cantonensis infection in 98 clinically diagnosed cases from three highly endemic districts in Khon Kaen province were 39.79% and 37.75%, respectively. Among 86 sera of subjects at risk of infection with A. cantonensis, 24.41% were positive by DIGFA and 23.25% by dot-blot ELISA. There were good correlation between the visual grading of DIGFA and dot-blot ELISA in both groups of defined sera. DIGFA is as sensitive and specific as dot-blot ELISA for confirming eosinophilic meningitis due to A. cantonensis infection, with advantages of simplicity, rapidity and without the use of specific and expensive equipment, and can be used in field settings.

    PMID: 23202608
    Trichuris dysentery syndrome is caused by Trichuris trichiura which contributes to one of the most common helminthic infections in the world. It is associated with heavy colonic infection that manifests as mucoid diarrhoea, rectal bleeding, rectal prolapse, iron deficiency anaemia, and finger clubbing. Here, we report a case of trichuris dysentery syndrome complicated with severe chronic iron deficiency anaemia in a 4-year-old girl who required blood transfusion. The nematode was visualized on stool microscopic and colonoscopic examination. A longer duration of anti-helminthic treatment is required to achieve effective and better outcome.
